# Note that we must not copy the files by python's internal utilities
# here, such as shutil.copy, or loops written manually, etc., because it
# would cause ETXTBSY in run_subprocess called below if we run this
# on multi-threading. Here is the senario:
# Let there are two cases A, and B, and, to simplify, let what we do here
# are 1) copying the "{A_src,B_src}/build" files to "{A,B}/build", and then
# 2) fork() and execute() "{A,B}/build". Each will run on a different
# threads, named thread-A and thread-B.
# 1) on thread-A, "A_src/build" is copied to "A/build".
# 2) on thread-B, "B_src/build" starts to be copied to "B/build". For that
# purpose, "B/build" is opened with "write" flag.
# 3) on thread-A, the process is fork()'ed, *before the copy of "B/build"
# is completed. So, subprocess-A keeps the FD of "B/build" with "write".
# 4) on thread-B, "B/build" is copied, and close()'ed, then fork()'ed.
# 5) on subprocess-B, it tries to exec "B/build". However, the file is
# still kept opened by subprocess-A. As a result, ETXTBSY is reported.
# Probably, the ideal solution would be that such an issue should be
# handled by the framework (crbug.com/345667), but it seems to need some
# more investigation. So, instead, we copy the files in another process.
